843 eSDHC1 for only SD card. The hardware workaround is recommended to use
844 an on-board level shifter that is 1.8v on SoC side and 3.3v on SD card
845 side. For boards without hardware workaround, this option could be
846 enabled, ensuring 1.8v IO voltage and disabling eSDHC if no card.
847 This option assumes no hotplug, and u-boot has to make all the way to
848 to linux to use 1.8v UHS-I speed mode if has card.
